What Causes the Car's Hazard Lights to Keep Flashing?

[LaIsaac]

Reasons why the car's hazard lights keep flashing: If the hazard lights won't turn off, it's most likely due to a malfunction in the control box. You should check if the hazard light relay is functioning properly. Use a multimeter to test the output line of the hazard light relay to see if there is a 12v output. Engine oil warning light on: In many cases, it indicates low engine oil level, and adding oil is relatively simple. Coolant temperature warning light on: This usually indicates overheating. When the coolant temperature in the radiator reaches 100 degrees while driving, the temperature warning light will illuminate. Tire pressure warning light on: Determine whether the pressure is too high or too low. Excessive pressure can lead to tire blowouts while driving, so the tire pressure should be reduced. The battery indicator light is used to display the working status of the car battery, and its color is usually red or yellow.
